Phlox plant named ‘Duephopin’

ABSTRACT

A new and distinct cultivar of  Phlox  plant named ‘Duephopin’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; freely flowering habit; and large light red purple-colored flowers.

Botanical designation: Phlox maculata.

Cultivar denomination: ‘DUEPHOPIN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phloxplant, botanically known as Phlox maculata and hereinafter referred toby the name ‘Duephopin’.

The new Phlox plant is a product of a planned breeding program conductedby the Inventor in Rheinberg, Germany. The objective of the breedingprogram is to create new compact Phlox plants with unique and attractiveflower color.

The new Phlox plant originated from an open-pollination in Rheinberg,Germany in July, 2006 of a proprietary selection of Phlox maculataidentified as code number PH-05-0310-1, not patented, as the female, orseed, parent with an unknown selection of Phlox maculata as the male, orpollen, parent. The new Phlox plant was discovered and selected by theInventor as a single flowering plant within the progeny of the statedopen-pollination in a controlled greenhouse environment in Rheinberg,Germany in May, 2009.

Asexual reproduction of the new Phlox plant by cuttings in a controlledenvironment in Rheinberg, Germany since May, 2009 has shown that theunique features of this new Phlox plant are stable and reproduced trueto type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phlox plant have not been observed under all possibleenvironmental and cultural conditions. The phenotype may vary somewhatwith variations in environmental conditions such as temperature andlight intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duephopin’. These characteristics incombination distinguish ‘Duephopin’ as a new and distinct Phlox plant:

-   -   1. Compact, upright and outwardly spreading plant habit.    -   2. Freely branching habit.    -   3. Freely flowering habit.    -   4. Large light red purple-colored flowers.

Plants of the new Phlox can be compared to plants of the female parentselection. Plants of the new Phlox differ primarily from plants of thefemale parent selection in the following characteristics:

-   -   1. Plants of the new Phlox are more compact than plants of the        female parent selection.    -   2. Plants of the new Phlox and the female parent selection        differ in flower color as plants of the female parent selection        have purple-colored flowers.

Plants of the new Phlox can be compared to plants of the Phlox ‘PhoenixPink Touch’, not patented. In side-by-side comparisons, plants of thenew Phlox and ‘Phoenix Pink Touch’ differed in the followingcharacteristics:

-   -   1. Plants of the new Phlox were more compact than plants of        ‘Phoenix Pink Touch’.    -   2. Plants of the new Phlox and ‘Phoenix Pink Touch’ differed in        flower color as plants of ‘Phoenix Pink Touch’ had        purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Phlox plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Phlox plant.

The photograph comprises a side perspective view of a typical floweringplant of ‘Duephopin’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the summer in 10.5-cm containersin a glass-covered greenhouse in Rheinberg, Germany and under commercialpractice. During the production of the plants, day and nighttemperatures averaged 18° C. and light levels averaged 4,500 lux. Plantswere pinched one time three weeks after planting and were 13 weeks oldwhen the photograph and description were taken. In the followingdescription, color references are made to The Royal HorticulturalSociety Colour Chart, 1995 Edition, except where general terms ofordinary dictionary significance are used.
